Kukulcania
Crevice Weavers
Kukulcania is a genus of crevice weaver spiders in the family Filistatidae, first described by Pekka T. Lehtinen in 1967 and named after Kukulkan, a Mesoamerican serpent deity. The genus contains fifteen species distributed across the Americas, from the United States through Mexico and Central America to South America. These spiders are characterized by their cribellate silk production and distinctive sexual dimorphism. The most widespread species, Kukulcania hibernalis, is highly synanthropic and has been introduced to multiple regions outside its native range.
